The law does *forbid* you from making a patented item even for your own
use. (From
http://www.uspto.gov/web/offices/pac...x.html#patent: "The
right conferred by the patent grant is, in the language of the statute
and of the grant itself, “the right to exclude others from making,
using, offering for sale, or selling” the invention in the United States
or “importing” the invention into the United States." Notice the word
"making".)

But the law doesn't *prevent* anyone from doing anything they like, as
long as they're not caught. This general attitude is also common among
people who pirate software, music, and other copyrighted items, as well.
